Question

ifax^2+bx+c=0,a is not equal to zero has real and repeated roots,then: A) b^2-4ac<0 (B) b^2-4ac>-0 (C) b^2-4ac>0 (D) b^2-4ac=0

Answer 1

D) b^2-4ac=0.....
hope this helps you

Answer 2

Hi ,

ax² + bx + c = 0 , a ≠ 0

If roots are real and equal then

b² - 4ac = 0

Option ( D ) is correct
